I did both. I burned from DVDA and I created the image and burned from IMG burn. It involves 3 separate duplicators and 4 brands of media including verbatim. The only constant would be the 1 year old DVD burner in my computer. I burned them and played them to test first before trying. 2 separate sandyyang 1-5 and a 1-7 with 2yr old board.
Just seeing if there is anything else I can try. I need to get a dance recital out with 50 copies of 2 discs a piece
As for discs Verbatim are no longer produced by Mitsubishi Chemical Corporation as they sold out to CMC Magnetics last year. I mention this as they were a favourite for reliability when produced by MCC. I have some Verbatim BD-RE (Blu-ray rewritables), purchased in 2014, which aren't actually made by MCC (they are CMC) and they are giving me bad burns after about 30 burns. A new disc from the same box gives no problems and neither do my genuine Verbatim BD-R discs. With disc burning rapidly declining the availability and quality of discs may become an issue for those of us that still burn discs.
